Answer:
The correct answer is 16.
Step-by-step explanation:
Number of chaperones required for 96 students is 12.
Thus under each chaperone there are [tex]\frac{96}{12}[/tex] = 8 students.
Now a total of 125 students are supposed to be sent on a trip.
Therefore the total number of chaperones required for these 125 students are [tex]\frac{125}{8} = 15.625[/tex] ≈ 16. (converted to the highest integer because the leftover 5 students would need one more chaperones)
Therefore a total for 16 chaperones are required by the Wachusett Perineal School to take 125 students for a field trip.
